How to Serve The Best Monster Cookies
You can serve monster cookies warm, straight out of the oven, or let them cool completely before serving. They pair well with a glass of milk, coffee, or a scoop of ice cream for an extra treat. You can also plate them nicely for parties or simply store them in a cute jar for snacking at home.
How to Store The Best Monster Cookies
To keep your cookies fresh, store them in an airtight container at room temperature. They can last for about a week. For longer storage, you can freeze them. Just ensure they are completely cooled, place them in a freezer bag, and freeze for up to three months. When you’re ready to enjoy them, let them thaw at room temperature.
Tips to Make The Best Monster Cookies
- Make sure to use smooth peanut butter for a better consistency in the cookie dough.
- If the dough feels too sticky, you can refrigerate it for about 30 minutes before scooping.
- Don’t overbake! Keep an eye on the cookies; they will continue to cook a bit on the cookie sheet after you take them out of the oven.
Variation
If you want to switch things up, you can add dried fruit, nuts, or even swap out the M&M’s for other candies. You can also use different nut butters, like almond or cashew, for a unique twist.
FAQs
Can I use creamy or chunky peanut butter?
You can use either, but creamy peanut butter will give you a more even texture.
Why are my cookies flat?
If your cookies are flat, it might be due to overmixing or not using enough flour. Ensure your baking soda is fresh as well.
Can I make these cookies gluten-free?
Yes! Use gluten-free oats instead of regular rolled oats to make gluten-free monster cookies.
